POWER OF BACKQUOTES

Backquotes are the most powerful things in Unix. More than one
Unix commands can be run simultaneously on the prompt.
In csh,

% find . -name "*.txt" -print

gives the path & names of the files with extension ".txt" in
current directory and its subdirectories. If you want to open
these files in vi together then

% vi `find . -name "*.txt" -print`

Similarly,

% find . -name "*.txt" -print
<listing of all txt files. in current directory/sub-dirs>
% vi `!!`

this will open all those files in vi listed by find command.
